SMF 4 series - SMF228/SMF229

Relay module with 4-pole relay with forcibly guided contacts according to IEC 61810-3, application type A for mounting on 35 mm rail. With notched-crown contacts for switching currents from 3 mA to 8 A ideally suited for both monitoring circuits and load circuits.
Simplified installation due to plug-in terminals with screw and push-in technology.
Display of the control and protective circuitry are already an integral part of the module. Shortest possible release times of the switching contact are guaranteed by the use of a TVS diode.

Switching current: 3mA - 8A
Test voltage (rms): 4000V
